Abstract

The present invention relates to a filter element and a filter having the filter element. The filter element comprises a filter element housing part, a water inlet disposed at the filter element housing part, a filter medium unit disposed in the filter element housing part, and a central pipe. The central pipe comprises a pure water collecting pipe and a wastewater collecting pipe, and the wastewater collecting pipe is at least partially disposed in the pure water collecting pipe. A wastewater passage and a pure water passage are arranged sequentially from the center to the circumference in the central pipe. The filter element and the filter according to the present invention has a more simplified filter element structure. By reducing the quantity of components, the filter is made more compact. The present invention can further accommodate positional errors within an allowed error range when the filter element is mounted to a local manifoldof the filter. Manufacturing precision requirements of filter components can thus be lowered and the cost can be reduced. The replacement and mounting of the filter element have therefore become easier.
